Description

Technical Field

[0001] The utility model relates to the technical field of knife ring processing equipment, in particular to a mold locking device for knife ring production. Background Art

[0002] The roller cutter is an important part of large-scale mechanical equipment for full-section construction of underground rock tunnel projects. It is mainly used for full-section construction of railway and highway traffic tunnels, coal mine tunnels, urban underground passages, hydropower and water conservancy tunnels, etc. The main parts of the roller cutter are the cutter body, cutter ring, cutter ring retaining ring, seal, bearing, spindle and end cover. During the tunnel excavation process, the wear and extrusion between the roller cutter ring and the rock will cause the cutter ring to wear, heat and deform. When the roller cutter ring heats up, its hardness decreases, thereby accelerating wear. By using centrifugal casting to produce super wear-resistant bimetallic roller cutter rings, the problem of short roller cutter ring life can be effectively solved.

[0003] When processing different knife rings, different knife ring molds need to be replaced, so the molds need to be locked and disengaged. In order to prevent the movable mold and the fixed mold from deflecting or displacing, the conventional method is to lock the movable film and the static film by a locking screw, and to disengage the locking screw, because the locking screw needs to be rotated for both locking and disengaging, which wastes a lot of time and reduces work efficiency. Therefore, the utility model provides a mold locking device for knife ring production. Utility Model Content

In order to prevent the movable mold and the fixed mold from deflecting or displacing, the conventional method is to lock the movable film and the static film by a locking screw, and to disengage the locking screw, because the locking screw needs to be rotated for both locking and disengaging, which wastes a lot of time and reduces the work efficiency. A mold locking device for knife ring production is proposed.

[0019] Reference Figure 1-6 As shown, the utility model provides a technical solution: a mold locking device for knife ring production, including a base 2 and a workbench 1, the upper surface of the base 2 is fixedly connected with a mold body 3, and the inner surface of the lower end of the base 2 is provided with four limiting holes 10, the workbench 1 is provided with two moving grooves 5, the inner wall surfaces of the two moving grooves 5 are provided with two slide grooves 6, the inner walls of the slide grooves 6 are slidably connected with sliders 7, and one end of the slider 7 is fixedly connected with a T-shaped limiting frame 8, the lower end of the T-shaped limiting frame 8 is provided with a driving assembly, and the upper end of the T-shaped limiting frame 8 is slidably connected with two limiting rods 9, one end of the limiting rod 9 is slidably connected to the inner wall of the limiting hole 10, and the other end of the limiting rod 9 is slidably sleeved with a limiting spring 11, the limiting One end of the limiting spring 11 is fixedly connected to the limiting rod 9, and the other end of the limiting spring 11 is fixedly connected to the side wall of the T-shaped limiting frame 8. The base 2 is placed on the surface of the workbench 1, and the two T-shaped limiting frames 8 are driven by the driving assembly to move in the direction close to the limiting hole 10. At the same time, the sliders 7 on both sides slide in the slide groove 6, which plays a guiding and limiting role. When the limiting rod 9 on the T-shaped limiting frame 8 is inserted into the limiting groove of the base 2, the limiting rod 9 will squeeze the limiting spring 11. The reaction force generated by the deformation of the limiting spring 11 can make one end of the limiting rod 9 close to the inner wall of the limiting hole 10, thereby quickly locking and fixing the mold base 2 and improving the work efficiency of installing the mold.

[0020] Reference Figure 3 , Figure 5 and Figure 6As shown, in this embodiment: the driving assembly includes a threaded rod 14, the upper end of the threaded rod 14 is fixedly connected to the lower surface of the workbench 1, and the surface of the threaded rod 14 is slidably connected to the ring plate seat 13, the surface of the ring plate seat 13 is rotatably connected to the movable rod 12, and the other end of the movable rod 12 is rotatably connected to the lower end of the T-shaped limit frame 8, and a rotating handle 15 is arranged below the ring plate seat 13, and the rotating handle 15 is threadedly connected to the threaded rod 14. When the rotating handle 15 is rotated, the rotating handle 15 pushes the ring plate seat 13 upward with the help of the thread, and the ring plate seat 13 moves upward while driving the movable rod 12 to rotate. When the rod 12 rotates, it pushes the T-shaped limit to move in the moving groove 5, thereby driving the T-shaped limit frame 8 to move. A return spring 16 is fixedly connected to the upper surface of the ring plate seat 13, and the other end of the return spring 16 is fixedly connected to the upper end of the threaded rod 14. When the base 2 needs to be disassembled, the rotating handle 15 is rotated, and the rotating handle 15 moves downward with the help of the thread. At the same time, the return spring 16 restores its elastic deformation, pushing the ring plate seat 13 to move downward, causing the movable frame to rotate and drive the limit rod 9 on the T-shaped limit frame 8 to move in the direction away from the limit hole 10, thereby achieving the effect of quick disassembly.

[0021] Reference Figure 2 and Figure 4 As shown, specifically, a slot 18 is provided on the inner surface of the lower end of the base 2, and a block 17 is fixedly connected to one side of the T-shaped limit frame 8, and the block 17 is slidably connected to the inner wall of the slot 18. When the T-shaped limit frame 8 moves to insert the limit rod 9 into the limit hole 10, the block 17 on one side of the T-shaped limit frame 8 is also inserted into the slot 18, so that the T-shaped limit frame 8 and the base 2 can be limited to prevent it from shaking, thereby achieving the effect of enhancing stability. Four positioning blocks 4 are fixedly connected to the surface of the workbench 1, and the cross-section of the four positioning blocks 4 is "L"-shaped, and the four positioning blocks 4 are symmetrically arranged and distributed. By setting the positioning blocks 4, the position of the base 2 can be preliminarily fixed, thereby facilitating the insertion of the limit rod 9 into the limit hole 10.

[0022] Working principle: place the base 2 between the four positioning blocks 4, and the position of the base 2 can be preliminarily fixed by the positioning blocks 4, so that the limiting rod 9 can be inserted into the limiting hole 10 conveniently, and then rotate the rotating handle 15, and the rotating handle 15 pushes the ring plate seat 13 upward with the help of the thread, and the ring plate seat 13 moves upward while driving the movable rod 12 to rotate. When the movable rod 12 rotates, it pushes the T-shaped limiting frame 8 to move in the direction close to the limiting hole 10, so that the sliders 7 on both sides of the T-shaped limiting frame 8 slide in the slide groove 6, which plays a role of guiding and limiting. When the limiting rod 9 on the T-shaped limiting frame 8 is inserted into the limiting groove of the base 2, the limiting rod 9 will squeeze the limiting spring 11, and the reaction force generated by the deformation of the limiting spring 11 can make one end of the limiting rod 9 close to the inner wall of the limiting hole 10, thereby quickly locking and fixing the mold base 2, thereby improving the working efficiency of installing the mold.
